Created attachment 6766 [details] this is .config file which make this problem. Hi, I have compiled raspberry pi 3 image with config file attached here. Unfortunately at the very last stage I had manually link ln -s rootfs.ext2 rootfs.ext4 in the images/ directory, then run make again and it assembled sdcard.img When I used default rpi3 config it was not the case, so it is something in my custom config, which is default based. It seems it is something minor. Thank you Mikhail
You set BR2_TARGET_ROOTFS_EXT2_GZIP=y, so the symlink will be rootfs.ext4.gz -> rootfs.ext2.gz instead of rootfs.ext4 -> rootfs.ext2. If you make such a change you have to adapt the post-image script.
Thank you very much! Mikhail
